URL Lowercase

Solution

URLs should be lowercase to prevent duplicate content issues. Most servers treat /Page and /page as different URLs, creating duplicates. Always use lowercase URLs and redirect uppercase variants. Configure your server or CMS to auto-lowercase URLs. This also improves URL consistency and readability.
